Fees you cannot see
£40,000 of sales, £6,000 in the bank, and no one can tell you where the rest went. Referral, fulfilment, storage and advertising come out before your payout. A generalist buries them in one revenue line.

Sound familiar?
The pain points no one warned you about.
Stock booked at the wrong time
Most accountants expense stock the day you buy it, not the day it sells. That breaks your margin per product and makes a good month look bad, and a bad month look fine.
VAT left on the table
There is often reclaimable VAT sitting inside your Amazon fees. A generalist who has never opened a settlement report will not find it, so you quietly overpay.
Books that never match Seller Central
Returns, reimbursements and disbursements land on different days. If nobody reconciles the settlement report, your accounts and your Seller Central balance never agree.

Why us
Why choose Zmartly for amazon fba sellers.
01 Built for FBA, Not Generalist
As a specialist Amazon accountant, we live in Seller Central settlement reports. Referral fees, FBA fees, storage, PPC, every line categorised correctly so your P&L is real.
02 Per-SKU Profit, Not Just Revenue
COGS recognised when stock sells, not when you buy it. You finally see which products actually make money after Amazon takes its cut.
03 VAT Done Right Across Markets
UK, EU OSS, and IOSS handled together, no double-paying, no missed reclaims on storage and ad spend.
The detail
Why do Amazon’s numbers break normal bookkeeping?
Amazon does not pay you per sale. It pays a lump sum every two weeks, after taking referral fees, Fulfilment by Amazon (FBA) fees, storage, advertising and refunds out of the total. A high-street accountant records that payout as revenue and stops there, so your real margin disappears. Good amazon seller accounting works the other way round: a specialist Amazon accountant pulls the settlement report, splits out every fee line, matches refunds and reimbursements to the right orders, and recognises the cost of goods sold (COGS) when the stock sells, not when you buy it. The result is a profit and loss you can trust, by product and by month.
What does an accountant for Amazon sellers actually do?
Everything your Amazon business needs sits under one fixed monthly fee. As your accountant for amazon sellers, we cover four things. Amazon bookkeeping services reconcile every Seller Central settlement through A2X or Link My Books, so your books tie to real sales. Amazon VAT services register you when you need it, file your returns, and reclaim the VAT that generalists leave inside your fees. We prepare your year-end accounts, your Corporation Tax or Self Assessment, and your amazon tax return, filed on time with the bill flagged early. And amazon business advisory shows profit per product and models the right structure for your stage. One team of qualified accountants (ACMA, CGMA, ACCA, FCCA).
How does VAT work for Amazon FBA sellers across the UK and EU?
Value added tax (VAT) is the biggest risk area in amazon fba accounting. If your business is UK-based, you must register once your taxable turnover passes the VAT registration threshold over any rolling 12-month period, and it is total sales, not profit, that gets you there. Once Amazon moves your stock abroad under Pan-EU FBA, you often need local VAT registrations too. We file under the One Stop Shop (OSS) for European Union sales and the Import One Stop Shop (IOSS) for low-value consignments, and reconcile the VAT Transactions Report each month so nothing falls between countries.
Which accounting software do you use for Amazon sellers?
Clean numbers start with the right connections. We are an a2x accountant, and we also work with Link My Books, so every settlement, fee and refund flows into the ledger correctly rather than as one monthly figure. As your Amazon accountant, we build your chart of accounts around how Amazon actually pays, then run it through Xero for Amazon sellers, or QuickBooks for Amazon sellers if you prefer. Either keeps you ready for Making Tax Digital (MTD), the HMRC rule that requires digital VAT records.
Who do you work with, from sole trader to limited company?
From your first £1,000 of sales to seven figures, we match the work to your stage. As a specialist amazon fba accountant, we handle private label, wholesale, arbitrage and seller-fulfilled sellers alike. Starting out, we act as your amazon sole trader accountant, keeping Income Tax and National Insurance simple through Self Assessment. As profit grows we become your amazon limited company accountant, moving you to a salary and dividend mix once it is worthwhile and telling you honestly when that point arrives. If you also sell on Shopify, eBay or Etsy, we bring those channels into the same books.

What does a fixed-fee ecommerce accountant cost, and is switching hard?
Our fees are fixed and set by your transaction volume, never billed by the hour. Plans run from £129 a month for Essentials up to £499 a month for larger, multi-market sellers, covering bookkeeping, VAT, accounts and support with replies inside 72 hours. As an ecommerce accountant uk sellers can move to in days, switching is easy: we contact your old accountant, transfer your records, and rebuild your books in week one. Terms are rolling monthly with a 30-day money-back guarantee, so there is no long contract to escape. Most sellers find a good Amazon accountant pays for itself through reclaimed VAT and cleaner margins.
What do you get each month?
Every month you get a clean set of numbers and a person who answers. We reconcile your Seller Central settlements, update your bookkeeping, and send a profit and loss by product, so you can see which lines actually make money once Amazon has taken its cut. Your VAT position is checked, your filing deadlines are tracked, and anything that needs a decision is flagged early rather than sprung on you at year end. As your Amazon accountant, we stay on email with replies inside 72 hours, so a quick question never waits a week for an answer. That is the difference between numbers you chase around a spreadsheet and numbers you can actually plan the next quarter around. No chasing, no year-end surprises, just a clear picture you can act on.
Questions? We’ve got answers
The most common questions.
We pull the full settlement report from Seller Central (or via A2X / Link My Books into Xero) and categorise every line: referral fees, FBA fulfilment, storage, PPC, refunds, reimbursements, and disbursements. Reconciling only the bank deposit is how generalists hide fees inside revenue and break your true margin. You see a real P&L by SKU, not a Frankenstein number.
Where Amazon charges UK VAT on your seller fees, that VAT is reclaimable on your VAT return if you are VAT-registered. We review your recent fee invoices, identify reclaimable VAT on storage, advertising and fulfilment, and submit the correction. The amount depends on your fee volume, and we tell you what to expect before we file.
Yes. We register and file UK VAT, EU OSS for B2C distance sales, and IOSS for sub-€150 imports, plus local VAT registrations wherever Amazon stores your stock (DE, FR, IT, ES, PL, CZ). We reconcile the VAT Transactions Report monthly so nothing falls between jurisdictions and you never double-pay.
If they expense inventory at purchase instead of at sale, miss reclaimable VAT on FBA fees, or hand you a single-line P&L, you are almost certainly overpaying tax and flying blind on margin. We handle the entire handover (HMRC re-authorisation, records transfer, Xero rebuild) in week one with zero effort from you, and most FBA clients recover our annual fee within the first VAT return.
Fixed monthly pricing from £129 (Essentials) up to £499 (Enterprise), covering bookkeeping, VAT, year-end accounts and unlimited email support, replies inside 72 hours, every message. Onboarding takes 5-10 working days from signed engagement letter, with a 30-day money-back guarantee and rolling monthly terms, so there is no long contract to escape if it isn't a fit.
If your business is established in the UK, you must register once your taxable turnover passes £90,000 in any rolling 12-month period, and you have 30 days from the end of the month you cross it. It catches sellers out because it is total sales that count, not profit, so FBA volume gets you there faster than you expect. You can also register voluntarily below £90,000 to reclaim VAT on Amazon fees and stock. If you are based outside the UK but hold stock here, no threshold applies and you register from your first sale. We watch your rolling turnover and register you at the right moment, so you neither miss the deadline nor jump early.
Both. Fulfilment by Merchant (FBM), where you store and ship your own stock, has a different cost and VAT profile to Fulfilment by Amazon (FBA), and many sellers run the two side by side. We reconcile whichever mix you use, track profit by fulfilment method as well as by product, and handle the VAT treatment for each. If you move stock between FBM and FBA as you grow, your books stay consistent throughout.
